  1. gitlab

    I'm not sure I personally agree with this, and I'm not 100% sure the developer community at-large does either...

    Let's take a few examples, which I've shared elsewhere in similar discussions:

    - GitLab: Open Source or Open Core? Most would say Open Source, but (I assume) you would argue Open Core [0].

    - Plausible: Open Source or Open Core? They say Open Source, but it's actually Open Core [1].

    - Cal.com: Open Source or Open Core? They say Open Source, but once again, Open Core [2].

    - Posthog: Open Source or Open Core? They say Open Source, still Open Core [3].

    - Sidekiq: Open Source or Open Core? Once again: Open Core [4].

    Yet, every dev I know would consider these projects Open Source. So there's a disconnect somewhere.

    Under this mindset, very few open source startups are actually open source, yet everybody says they are?

    I'm not trying to argue either way; I'm trying to point out a disconnect here.
